The height of a right cylinder is 3 times the radius of the base. The volume of the cylinder is 242What is the height of the cylinder?2 units4 units6 units8 units

Answer:DStep-by-step explanation:FormulaVolume = pi*r^2*hGivensr = xh = 3xVolume= 242Solution242 = pi * x^2 * 3x242 = 3.14 * 3x^3                    Divide by pi242/3.14 = 3.14 * 3x^3 / 3.14   Do the division 77 = 3x^3                                 Divide by 377/3 = 3x^3 /325.69 = x^3                              Take the cube root of both sides.2.95  = xThe height of the cylinder is 3 times that of the radius of the circle (x)The answer is 8.85. I suppose the closest answer is 8.
